Stop the flow of water by turning the faucet knob completely clockwise until tight.
Insert the female end of the first hose into the threaded male coupler that comes in the quick-connector package. Twist the two parts together until tight.
Insert the male end of the second hose into the female half of the quick-connector set. Screw together until tight.
Pull back the slide on the male quick-connector on one hose and push into the female quick-connector on the second hose. Release the slide to lock the two hoses together. Some quick-connector sets also require a half-twist to lock the two halves together.
Open the water valve on the faucet to use the two interconnected hoses.
